在Python上安装xgboost-找不到频道

Question

我尝试使用以下方法安装xgboost：

pip install setuptools
conda config --add channels conda-forge 
conda install xgboost

收到以下错误：

Solving environment: failed

PackagesNotFoundError: The following packages are not available from current  channels:

已安装setuptools

不确定什么是行不通的。有什么想法吗？
